I, Witness is a gripping psychological mystery thriller with a great premise.

The story starts with an intriguing and disturbing prologue and continues with increasingly thrilling chapters told from multiple viewpoints. The book is compelling from the start but I particularly raced through the last 50% in one sitting.

I loved Madison: grumpy, sweary, damaged, rock-loving Madison Attalee, who has her own mysterious background and does not suffer fools gladly. Kate is a sympathetic character and all the narrators (not wanting to spoil who those are) bring something to the plot. There are some interesting and clever parallels drawn between some of our main protagonists.

Niki Mackay has written a really well-plotted story; it is dramatic and emotional; it is dark and twisted and chilling. I would recommend this to anyone who likes a good, complex psychological thriller to really get their teeth into and I look forward to her next book!
